P. Iacconi et al., THERMOSTIMULATED EXOELECTRONIC EMISSION AND THERMOLUMINESCENCE OF VARIOUS ALPHA-AL2O3 SAMPLES, Physica status solidi. a, Applied research, 139(2), 1993, pp. 489-501
A systematic study of TSEE curves obtained after UV or X irradiations
at 77 K from alumina samples of various origin is reported. These curv
es are systematically compared with TL glow curves recorded in similar
conditions. Nine positions for thermostimulated peaks are detected in
the 77 to 600 K range. These peaks appear with various occurrence fre
quencies. Except for the first peak (100 K, peak A) which does not exi
st in the majority of the TSEE curves recorded, the main TSEE peaks co
incide fairly well with the correspondent TL peaks. A mechanism is pro
posed to interpret the behaviour of peak A.
